An aerodynamic design method and corresponding codes have been developed for three dimensional multi-lifting surfaces at transonic flow. It is based on the "iterative residual coreection" concept that is succesfully used for transonic wing and subsonic multi-lifting surface design. An upwind scheme is introduced into the governing equations for the multi-lifting surface design method and schwitched on automatically when supersonic flow appears on the surface. A series of interface codes have been programmed, including a target pressure modification tool. The transonic multi-lifting aerodynamic design software includes the improved inverse aerodynamic design code, the DLR-TAU code for Navier-Stokes/Euler CFD analyis and interface codes. Two cases of a canard-wing configuration have been tested to validate the methods and codes. The results show that the analysis/design iterations converge at higher transonic flow.
